Problem:What will happen (to the balloon) when we put the bottle in the hot and cold water. Research: You didn't include any background information. Hypothesis:If we put the bottle in the hot water then it(the bottle?) might expand(What will happen to the balloon when the bottle is placed in cold water?) Materials: Safety goggles,Balloon,Plastic bottle,Warm water,Cold water Procedure: 1.)Stretch the opening of the balloon over the neck of the bottle. 2.)Observe the balloon at room temperature. Record observations. 3.)Place the bottle with the ballon in the warm water for about 30 seconds.
4.) Observe the ballon again and record any changes you see in the balloon. 5.)Remove the bottle and ballon from the warm water and quickly place it in the cold
water for about 30 seconds (or until it cools).
6.) Observe the ballon and record any changes you see in the ballon. Results:
Water Temperature
Prediction
Description of the Balloon
Room Temperature
The Ballloon will do nothing.
it deflated
Warm
The balloon will blow up.
it got bouncy and popedm up
Cold
It will not do anything.
it actually deflated.
Conclusion: Are(Our) hypothesis is correct putting the bottle in the hot water made the balloon expand(What did you stated in your hypothesis? What did your results show to support this?)
I can state a hypothesis related to the problem and procedure.
I can conduct research about concepts that are related to the topic I am investigating.
I can collect quantitative/qualitative data while conducting an experiment.
I can use the data in my results to draw a conclusion about what happened and why.
Overall, I can apply the scienctific method to solve a problem.
